In 1720 the first organ was built by Ferdinand Josef Römer on the west gallery of the cathedral. This instrument had 32 registers, spread over 2 manuals and pedal, and was also known as the "Römer Orgel".


In 1886 the organ builder Eberhard Friedrich Walcker installed a monumental organ with 90 registers and 3 manuals in the existing case. Due to its size and the placement directly above the giant gate, the main portal of St. Stephen's Cathedral, the organ in the west gallery is now also referred to as the "Riesen Orgel". This important instrument was destroyed during the cathedral fire in World War II. A comparable but much smaller instrument can still be found in the ''Votiv'' Church in Vienna

I create this composite by spending months reworking and balancing different ranks of existing pipes to produce a sound as close as possible to the real former sound. Although it does not contain ranks sampled from the real instrument, the mix specifications have been copied to increase the realism of the composite. Many of the ranks will be reworked in such a way that the organist will have a perspective that was probably experienced on this organ before 1945.
